英文摘要	Coastal wetland,at the intersection of land and sea,is considered as asink,source,andtransformerof phosphorus(P). Coastal wetland plays an important role in the global P cycle,and its ability to retain excessive P in water receives increasing attention. In this study,the coastal reed wetland sediments surrounding the Bohai Sea were sampled to investigate P adsorption capacity and loss risk by conducting batch experiments. Results show that the maximum P adsorption capacity(Q_(max))was 693.7-2 117.2 mg·kg~(-1),with an average of 1 468.6 mg·kg~(-1). The Q_(max) decreased in the order of Qilihai Wetland >Beidagang Wetland >Nandagang Wetland >Liaohe Delta Wetland >Shouguang Coastal Wetland >Yellow River Delta Wetland. The P adsorption capacity was related to the contents of Ca,Mg,and TOC. The degree of P adsorption saturation(DPS)and loss risk index(ERI)of the coastal wetland were 0.28%-4.50% and 0.53%-10.10%,respectively. The ERI suggested that the P loss risk was relatively low for coastal reed wetland surrounding the Bohai Sea except for the moderate loss risk for Shouguang coastal wetland. In summary,the reed coastal wetland around Bohai Sea demonstrated significantly P storage capacity and served as a P sink for water P. We recommend to fully utilize the coastal wetland to reduce point or non-point source pollution(e. g.,P)during the remediation or recovery of the polluted Bohai Sea.
